18. 500 men took dip in a tank which is 80 m long, 50 m broad. What is the rise in water level if thedisplacement of water by a man is 4 m[Hint. Volume of waler displaced by 500 men (4x 500)-2000 mArea of the tank = 80 x 50-4000 m2, let the rise in the level ofwater-h metres. Then 4000x h-20001 |
|
Answer» Level of water in the tank = hNow.,The amount of water rises in the tank = displacement of water taken by 500persons. 80*50*h = 500*44000h = 2000H = 2000/4000 m1/2m = 100/2cm = 50cm 50*10mm = 500mmThus,the rise of level of water in the tank is 500mm Level of water in the tank = hNow.,The amount of water rises in the tank = displacement of water taken by 500persons. 80*50*h = 500*44000h = 2000H = 2000/4000 m1/2m = 100/2cm = 50cm 50*10mm = 500mmThus,the rise of level of water in the tank is 500mm |

The perimeter of a rectangle is 28 cm whose area is 48 sq.cm. then find its measures.1.1 |
|
Answer» Let length of Reactangle = lLet breadth of Reactangle = b Perimeter of Reactangle= 2(length + breadth) 28 = 2(l + b)l + b = 14........ (1) Area of Reactangle= length * breadth l*b = 48b = 48/l...........(2) Put value of B from eq(2) in eq(1)l + 48/l = 14l^2 + 48 = 14ll^2 - 14l + 48 = 0l^2 - 8l - 6l + 48 = 0l(l - 8) - 6(l - 8) = 0(l - 6)(l - 8) = 0l = 6, 8 Therefore, If length = 6 cm, breadth = 8 cmIf length = 8 cm, breadth = 6 cm |

34.i) Define prisms and draw a rough diagram of a triangular prism. Also, verity theEuler's formula for the same.and edgesi) Define cylinder. Draw its rough diagram and write the number of facesof it. |
|
Answer» Prism is a polyhedron with two polygonal faces lying in parallel planes and with the other faces parallelograms Euler’s formula, F + V = E + 2 Here number of faces, F = 5 Number of vertices, V = 6Number of edges, E = 9Consider, F+V = 5 + 6 = 11E + 2 = 9 + 2 = 11Hence F + V = E + 2Thus Euler’s formula is verified A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom. No of faces =3No of edges=2 draw a net for a cube with an edge 3.5 cm |
